Abstract: Embodiments herein disclose a range detection system that includes a line-of-sight (LOS) emitter that outputs a LOS signal (e.g., visible light, infrared, etc.) which is detected at a receiver (e.g., a photodiode). The receiver outputs a signal representing the intensity of the LOS signal at the receiver. The output signal is converted into a digital signal which is then used to identify a distance value corresponding to the intensity of the LOS signal. For example, the range detection system may include a data structure that maps a plurality of digital signals to respective distance values. In this manner, the intensity of the LOS signal measured at the receiver can be correlated to a distance between the emitter and the receiver.

Abstract: In an interactive environment, a user action may dictate what type of action a base device performs using an entertainment object. In one embodiment, the base device includes a controllable electromagnet that uses magnetism to move one or more permanent magnetics mounted in or on the entertainment object. For example, the entertainment object may be a doll or character that jumps, vibrates, slides, or sways in response to a changing magnetic field generated by the electromagnet. Moreover, the user may wear headphones that determine the location of the base device (and the toy) relative to the user. Using this location, the headphones can output 3D positional audio that the user perceives as originating from the location of the entertainment object on the base device. The 3D positional audio can be outputted synchronously with the action performed by the entertainment object to further immerse the user in the interactive environment.
